PUMP.

' SPECIFICATION forming part of Letters Patent No. 263,944, dated September 5, 1882.

Application filed June 221882. (No model.)

To all whom it may concern:

Be it known that I, PHILIP A. MYERS, of Ashland, in the county of Ashland and State of Ohio, have invented a new and useful 1111- V The object of the invention is principally to so construct and organize the air-chamber and the submerged orlforcing cylinder of a forcepump that the whole may be contained within bored well or wellof small diameter.

My object is also to simplify the construction of the pump, and although it is designed principally for bored wells, it may be advantageously applied to general house and windmill use in open wells.

In the form which I have hereinafter shown I I have represented the pump with the larger and smaller pistons and cylinders oper- In the accompanying drawings, Figure 1 shows a side elevation of the pump; Fig. 2, a central longitudinal section of the same; Fig. 3, a modification for deep wells.

In these drawings the pump-barrel is represented at A. It is made preferably of ordi nary tubing. It may also be'of the same diameter as the cylinder B, of which it forms a and 2, from a point i above the cylinder B. Within this pump-barrel -I place a central tube, a, which may be made of ordinary gas-pipe. It is fixed to the cap I) of the pump-barrel by having-its upper end threaded and screwed into a hole tapped through the center of the cap. It is required only that the bore of this pipe a shall be large enough to admit the free play of the piston-rod 0. At a proper point upon the pipe a, on its extension into the cyl jcylinder, projecting belowiit a suitable distance, and to its lower end is screwed another Qtubular cap-piece,f, to which is fixed a submerged piston-cylinder, g, also of thin metal,

and held'securcly in its place by the cap-piece f. The air-cylinder d and the submerged cylinder g are slightly less in exterior diameter ;than the interior diameter of the main pipe or cylinder in which they are located, leaving an :annular water'space all around them. The piston-rod 0 extends through the pipe a. It is connected with the piston or plunger k in the submerged cylinder and with the lift-bucket e, of larger diameter than the plunger and working tight in the lower part of the cylinder 13.

j The ordinary suction-pipe, with its valve, is attached to the lower part of the cylinder 13 in the usual manner. V

I The discharge-spout G is of ordinary construction, and is located at any convenient place on the pump-barrel. Preferably I make and place it as shown, thereby leaving an ample air-space above the spout-opening of the barrel.

The cap bis fitted air-tight to the upper end of the pumpbarrel, and the upper end of the pipe at has also air-tight connections with the cap b.

The handle is of ordinary construction;

It will be apparentfrom the construction described that when the piston is operated by the handle or in any convenient way, and the through a like annular space around the aircylinder 01. When thus forced up it acts against the air within the air-cylinder. It also v the pipe 0-, in which the piston works.

as it rises acts against the air contained in the pump-barrel above the spout-opening, so that immediately after the stroke the reaction of .the air in the upper part of the pump-barrel is against the top of the column of water forcing it down. At the same time the reaction of the air within the air-chamber presses against the column of water at a point lower down and forces the column of water up. This gives a large amount of reaction and a very even flow of water. At the same time both air-chambers are compactly arranged within the same tubular structure, and no packings are required.

It will be' observed that both the cylinder 11, which constitutes the lower air-chamber, and the submerged cylinder g, are suspended by This gives a very simple and cheap construction. The cylindeng, as well as the upper cylinder are held in central position by the piston-rod itself, which, of course, is guided by the liftbucket, while the upper plunger maintains the submerged cylinder in a central position. For additional security I fix upon the outer surface of the submerged cylinder, at its upper and lower ends, small studsm m, which bear against the inner surface of the cylinder B.

With this construction, as above described,

I may use for the cylinder B pipe three inches (more or less) in diameter, which is adapted to bored wells, and by this means I avoid any necessity for enlarging the upper part of a bored well, and thereby forming a cavity liable to catch the surface-water and turn it into the well.

It will be apparent that the cylinder B may extend downward to any desired depth.

The same structure, though specially adapted to' bored wells, is so simple and compact that it may be advantageously used in open wells for general house and windmill use.

In Fig. 3 I have shown a form of the lower end of the pump adapted to deep wells. In this I do not extend the full-sized pipe B down to the cylinder of the lift-bucket, but provide a separate cylinder, H, connected to the lower end of the main cylinder by a pipe, it, through which the stern extends, connecting the larger lift-bucket to the piston above. In this case the displacement of the water by the upward motion of the bucket is the same; but there is a saving in the size of the pipe. The suctionpipe is of course fixed to the lower end of the lift-bucket cylinder, as in the form before shown.

Having thus described my invention, what I desire to secure by Letters Patent is- 1. In a force-pump and in combination, a central tube in the main pipe or cylinder, a

ing in said cylinder connected to the piston rod, substantially as described.

3. In a force-pump and in combination, a central tube connected by an air-tight central joint to the pump-cap, leaving an annular closed space in the tubeofthepump,apiston-rod working in said tube, and a submerged cylinder connected to the lower end of said tube and having a water-space between said cylinder and the inner surface of the pump-cylinder, a piston workingin said submerged cylinder, and a lift-bucket, all substantially as described.

4. In a force-pump and in combination, a

central tube connected by an air-tight central joint to the pump-cap, a piston-rod working in said tube, and an air-chamber placed upon said tube, with an aunular'space between its surface and the inner surface of the pump-cylinder, and suitable piston or pistons andvalves, substantially as described.

5. In a force-pump having a central tube, a, a submerged cylinder suspended therefrom, a central piston-rod, c, and piston working in said submerged cylinder, and a stern and liftbucket connected to said piston-rod, a separate lift-bucket cylinder, H, and intermediate pipe, h, substantially as described.

6. In a force-pump having a straight barrel or cylinder without offsets, adapted to a bored well, a submerged piston-cylinder connected to a pipe within the main cylinder and having a water-space between its periphery and the inner surface of the main cylinder, a piston working in the submerged cylinder, and aliftbucket working in the main cylinder, whereby the water is forced up past the submerged cylinder and within the main cylinder to the dis charge-spout, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PHILIP A. MYERS.
